Greetings,
I would like some guidance, suggestions, tips, and so on regarding detecting laser light.
This is a hobby project – really intended to play with an AVR – the laser I thought would be peripheral to the project.
I have picked a laser module from Digi-Key and would like to turn it on / off with my AVR and then detect it also with the AVR as either present or not (on / off).
I have Googled all types of phrases regarding detecting laser light and find lots of hits – unfortunately many have to do with detecting police laser.
I have found some stuff from Edmund Optics but I think it was too expensive.
I found a device from Burr-Brown that had a photo-diode and some amplification all in one part for around $60.00.
A co-worker said I could build something much cheaper than that for what I need.
Also when it comes to using a lens – from a hobby level – how do you mount a lens, how do you know it’s at the correct distance and so on?
Can you share tips and suggestions?
Thanks
